Hallo,

Ich habe mehrere Beomaster zu restaurieren, aktuell einen Beomaster 1001.

Bei den meisten sind noch die originalen Kondensatoren vorhanden.

Immer wieder liest man vom Austausch sämtlicher Tantal und Elkos  ( Recap).

Ist dieser Austausch

  • a  unumgänglich
  • b  nur notwendig bei defekt einzelner Kondensatoren
  • c   Schönheitsreparatur   ?

Bringt ein Austausch hörbare Ergebnisse +/- ?

 

Hello

I have several Beomaster to restore, currently a Beomaster 1001.

Most still have the original capacitors.

Again and again I read about the exchange of all tantalum and Elkos (Recap).

Is this exchange

     a. essential
     b. only necessary with defective individual capacitors
     c. Beauty repair?

Does an exchange deliver audible results +/-?

Hello

good question!

Elkos recap is essential with defective capacitors or in case you have bad musical performances, as usually happens with output capacitors.

About tantalium after 30-40 years change them is a advisable precaution.

In my opinon it's never a beauty option.

Hope this help

hello marco, thanks for your contribution to this little discussion.

I agree with the defective elkos must be exchanged in each case.

It is also known that tantalum capacitors are very critical. is there a really good replacement?

what about the other elkos?

Hello

in my restoration projects I replaced small value tantalium caps with plastic caps whilst for values above 1 microF replace with elkos.

About other elkos I prefer replace all with new one,  maybe after 30-40 years old elkos has yet right value but maybe fail after few hours.

Have a nice Friday
